Adding more lithium also enhances certain plasma properties aiding the reaction, the researchers found.http://phys.org/news240167592.html

Something similar occurs when one increases the electrical current flowing in a magnetized plasma doughnut: it takes on a wild helical shape, which spoils its performance. This phenomenon concerns scientists exploring fusion power, who use powerful magnetic fields to confine plasma during their experiments.http://phys.org/news176402729.html
